Metallurgical grade silicon carbide (SiC) with 88% -90% purity is a widely used material in the global steelmaking industry. It serves as an efficient steelmaking deoxidizer, carbon additive, and ferroalloy substitute, helping steel plants improve metallurgical efficiency while reducing production costs.
In modern steel production, many mills are actively seeking alternatives to traditional alloys such as ferrosilicon. Metallurgical silicon carbide 88% 90% provides both silicon and carbon in a single material, making it an effective solution for EAF steelmaking, converter steelmaking, and induction furnace smelting.
Due to its excellent high-temperature stability, strong reducing ability, and dual-element composition, SiC for steelmaking improves molten steel quality, enhances reaction efficiency, and reduces alloy consumption. For large steel plants and foundries with strict cost control requirements, bulk silicon carbide for metallurgy has become an important raw material in modern metallurgical processes.
Product Features
- High purity silicon carbide 88% 90% ensures stable metallurgical reactions in steelmaking furnaces.
- Dual composition of silicon and carbon provides both deoxidizing and carburizing effects.
- Excellent high-temperature resistance makes it suitable for electric arc furnace steelmaking and induction furnaces.
- Low impurity levels support the production of clean steel and high-quality alloys.
- Uniform particle size distribution ensures predictable dissolution and reaction speed.
Main Functions in Metallurgy
Metallurgical grade SiC performs several important functions in steel production:
- Steelmaking deoxidizer - effectively removes dissolved oxygen from molten steel.
- Carburizing agent for steelmaking - increases carbon content in molten metal.
- Ferrosilicon substitute - partially replaces FeSi in steel plants to reduce alloy costs.
- Slag modifier - improves slag fluidity and metallurgical reaction efficiency.
These advantages make metallurgical silicon carbide supplier products increasingly popular among global steel manufacturers and foundries.
